Susanne Göb received her Diplom (equivalent to an MSc) in geology with specialization in economic geology at the Eberhard Karls Universität Tübingen, Germany, in 2009. Her Diploma thesis, supervised by Gregor Markl, dealt with remobilization processes in hydrothermal veins from the Schwarzwald, Germany, with a special focus on rare earth elements. The paper that merited the Hawley medal is based on her MSc results. Currently, she is doing a PhD with Gregor Markl in Tübingen, where she investigates the formation of secondary minerals in vein-type ore deposits by combining the results of mineral and water analyses with thermodynamic modeling. Again, rare earth elements play a key role in her research. She expects to complete her PhD at the end of 2012.
Thomas Wenzel studied geology and mineralogy at the Bergakademie Freiberg, Germany. He completed an MSc thesis on the exploration of carnallitite deposits of eastern Germany in 1983. In his PhD, with H.-J. Rösler in Freiberg, he dealt with the distribution and formation of sulfate-rich potash seams in Thuringia. Since 1987, Thomas's scientific interests have changed to the mineralogy, petrology, and geochemistry of K-rich plutonic rocks, starting with the intrusive rocks of the so-called Meissen Massif in eastern Germany. In 1990, a Swiss Federal Fellowship enabled him to investigate the Meissen rocks by means of the electron-microprobe, XRF, cathodoluminescence and radiogenic isotopes at the University of Bern, Switzerland. He extended his investigations to other K-rich plutonic complexes of the Mid-European Variscan chain during a postdoc at the University of Mainz, and he finished with the habilitation in 1997. Between 1998 and 2001, Thomas worked with L. P. Baumgartner on the partial melting and assimilation of dolomitic xenoliths by mafic magma. In 2002, he went to the University of Tübingen, Germany, as a lecturer in polarization microscopy and igneous petrology. He is responsible for the electron microprobe lab. Thomas is a member of the DMG and MSA. He has published about 40 original peer-reviewed papers as first author or coauthor.
Michael Bau is a professor of geoscience at the School of Engineering & Science, Jacobs University Bremen, Germany. After graduating in geology from RWTH Aachen, Germany, Michael joined the Trace Element Geochemistry Group at the Hahn-Meitner-Institute, West Berlin (1989-1992). He received his doctoral degree in geochemistry from the Free University Berlin in 1991. He worked as a research associate in the Department of Ore Deposit Research at GFZ Potsdam, Germany (1993-1998), and at the NASA Penn State Astrobiology Research Institute, USA (1999-2002). Since 2003, Michael has been a professor of geoscience at Jacobs University Bremen, Germany, in the programs 'Earth and Space Sciences' and 'Integrated Environmental Studies.' His main research interests are low-temperature trace element and isotope geochemistry and the evolution of biogeochemical trace element cycles throughout Earth's history. His field of expertise is the aqueous, sedimentary, igneous, and environmental biogeochemistry of the rare earth elements and yttrium and other critical high-tech elements.
Dorrit Jacob is a specialist in trace element and isotope geochemistry at the Geocycles Research Center of the University of Mainz, Germany, where she works as both laboratory manager of the ICP-MS laboratory and leader of the new Biomineralization Group. She studied mineralogy for her MSc thesis in Mainz, establishing a microchemical technique for the analysis of three radiogenic isotope systems on single garnet grains. She moved on to a PhD at Göttingen, where she established the origin of eclogite xenoliths in kimberlites as former ocean crust of Archean age. Following this, she worked as a postdoc at the universities of Göttingen and Greifswald. In 2004 she moved to Mainz and set up a biomineralization research lab within the newly established Geocycles Research Center in 2006. She has twice set up a Laser-ICP-MS laboratory from scratch, in Greifswald and in Mainz. She is best known for her work on the microgeochemistry of eclogites and on the role of amorphous calcium carbonate as a precursor phase in the formation of carbonate biominerals.
Anselm Loges graduated in mineralogy (Diplom) at the University of Tübingen in 2008 with a thesis on the oxidation of silicon carbide. After this work in technical mineralogy, he completed his dissertation in petrology (University of Tübingen) on element transport, particularly of the REE, in hydrothermal systems. His thesis included studies of natural samples from southwestern Germany but also experimental work at McGill University, Montréal. In 2012, he joined the Mineralogy and Petrology Group at Technische Universität Berlin for his postdoctoral research. Anselm's primary field of interest is the hydrothermal transport of elements, with emphasis on quantitative thermochemical data for the complexation and speciation of HFSE and REE by naturally relevant ligands. His current research focuses on the interplay between volatile and highly insoluble elements and the implications of this interplay for ore-forming hydrothermal processes.
Gregor Markl completed in 1994 an MSc thesis on beryl- and Sn-bearing greisen systems in the Schwarzwald, Germany, after studies in physics, chemistry and mineralogy at Freiburg University, Germany. His PhD, with Kurt Bucher in Freiburg, dealt with halogen systematics in lower-crustal rocks from Lofoten, Norway. Since then, Gregor has worked on the petrology and geochemistry of hydrothermal ore deposits, of peralkaline rocks, of anorthosite-charnockite suites, and on REE systematics in various high- and low-temperature environments. In 1998 he was appointed professor of petrology at Tübingen University, Germany, and since 2005 he has been the chair of petrology at Tübingen. In 2001, he won the prestigious Krupp Award for Young University Teachers. In 2005-2006, he was president of the German Mineralogical Society (DMG). Since 2009, he has been a member of the German National Academy of Sciences Leopoldina. He has written 4 books and has published more than 100 peer-reviewed papers as first author or coauthor.
